In Sumerian mythology and later for Assyrians and Babylonians, Anu (also An; (from Sumerian *An = sky, heaven)) was a sky-god, the god of [[heaven, lord of constellations, king of gods, spirits and demons, and dwelt in the highest heavenly regions. It was believed that he had the power to judge those who had committed crimes, and that he had created the stars as soldiers to destroy the wicked. He was the father of the Anunnaku (also spelled Anunnaki).
Anu is a Vedic Sanskrit term for a non-Arya (non-Aryan) in the Rigveda, and the name of a non-Aryan tribe in RV 1.108.8, RV 8.10.5 (both times listed together with the Druhyu) and in the Mahabharata. One of the Anu kings, King Anga, was a chakravartin (AB 8.22).
